Winslet's rep has confirmed the wedding to ABC News, saying it was attended by the actress' "two children and a very few friends and family." The rep adds that the couple had been engaged since the summer.

Britain's Daily Mail further reports that Winslet's Titanic and Revolutionary Road co-star, Leonardo DiCaprio, gave away the bride, and that the couple's parents didn't know about the ceremony.

The 37-year-old Winslet and the 34-year-old Rocknroll, whose birth name is Abel Smith, reportedly have been in a relationship for over a year.

This is Winslet's third marriage; she was previously married to directors Jim Threapleton and Sam Mendes. She has one child with each ex-husband.

This is the second marriage for Rocknroll, who, like Winslet, is British.
